Issue with Save Tracks for Current User

[Plus18]

There is an issue with endpoint Save Tracks for Current User.

Let's add 5 tracks by request: A, B, C, D, E. The result will be in any order, but not in the order of the request. It could be B, C, E, A, D or C, A, B, D, E - it doesn't matter what the input is, the output will be random.

The same happen in Spotify UI when you move tracks via mouse from playlist to saved tracks.

My app allows users to transfer tracks from other platforms directly to Spotify saved tracks. Users are confused when they see the random order after the transfer is complete.
